StingingVelvet: Every forum I've ever used consistently has put a stop to multiple threads a day being started on the same issue. I don't think this is a GOG forum issue specifically, or a problem at all. It prevents clutter, spamming, repetitive content, etc. I think people are angry and want to vent and push GOG's buttons and that's fine, but keep it to one main thread on the issue like every forum ever would do.
To be fair, that sort of thing doesn't make a forum necessarily successful, though.
(i've seen sites that have multiple threads on the same topics that are very busy and fun to use as well, for example)
Not saying SOME threads shouldn't be closed, btw....just that there doesn't need to be one thread for everything.
(like this was autism: the forum)
